使用editext和两个按钮创建自定义对话框。

dilog.xml

<EditText
    android:id="@+id/editText1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:ems="10" >

    <requestFocus />
</EditText>

<Button
    android:id="@+id/ok"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_below="@+id/editText1"
    android:layout_marginLeft="30dp"
    android:layout_marginTop="20dp"
    android:text="OK" />

<Button
    android:id="@+id/anuluj"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignBaseline="@+id/ok"
    android:layout_alignBottom="@+id/ok"
    android:layout_marginLeft="35dp"
    android:layout_toRightOf="@+id/ok"
    android:text="Anuluj" />

</RelativeLayout>

在您的活动中，将自定义布局设置为对话框

public void showpopup()  
{
final Dialog d = new Dialog(MainActivity.this);
d.setTitle("my title");
d.setContentView(R.layout.dialog);
Button ok = (Button) d.findViewById(R.id.ok);
final EditText ed= (EditText) d.findViewById(R.id.editText1);
ok.setOnClickListener(new OnClickListener()
{

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        String s= ed.getText().toString();//get text form editext

    }

});
 Button anuluj = (Button) d.findViewById(R.id.anuluj);

    anuluj.setOnClickListener(new OnClickListener()
    {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            d.cancel();

        }

    });
    d.show();

   }
